BNSULATED HANGER FOR ARC-LAMPS.

{SPECIFICATION forming part of Letters Patent No. 655,762, dated August 1- 1, 1900.

Application filed May 4, 1900.

To all whom it may concern:

Be it known that I, GEORGE CUTTER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Insulated Hangers for Are- Lamps, (Case No. 1,) of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

Myinvention relates to devices for suspending arc-lamps or the like.

The principal object of the invention is to provide a simple, cheap, and durable hanger capable of properly insulating the lamp as as well as suspending it.

To the attainment of the foregoing and other desired ends my invention consists in matters hereinafter set forth.

In the accompanying drawings, Figure 1 is a View, partly in section and partly in elevation, of an arc-light hanger embodying my invention. Fig; 2 is a transverse section on line 2 2 in Fig. 1. Fig. 3 is a View of a detail of construction.

In the hanger illustrated in the drawings the lamp is supported by a hook A, which is preferably made in the form of a ring split longitudinally and made in two sections, one of which is pivoted to the upper part of the hook, as well shown in Fig. 3. The lamp is engagedby swinging the pivoted section upwardly, as shown in said figure, and passing the fixed portion of the ring through the eye in the lamp and then closing the pivoted ringsection downward and-into position, as shown in Fig. 1. The hook A is desirably supported by a bolt 13, to which the hook is threaded;

The bolt B is in turn supported by an insulator C, the bolt to such end being provided with a head 1 and the insulator with a flat supporting portion 2, upon which the head 1 can rest. The hole in the insulator C, through which the bolt B passes, is desirably made alittle larger than the bolt, whereby cracking and binding of the insulator are prevented.

The supporting-surface 2 of the insulator is desirably depressed below the top thereof, so as to form a recess or socket for the head Serial No. 15,436. (No model.)

;1 of the bolt B. The socket is preferably made to correspond, substantially, with the shape of the head 1, so as to prevent the lat- :ter from turning,and thereby allow the lam pholding hook orring A to be readily screwed on or 01f from the bolt.

The insulator C issupported by a couple of 'pins D D, extended transversely through it, as shown in Figs. 1 and 2. These pins D D are separated from one another by a distance less than the head 1 on the bolt B, as shown in Figs. 1 and 2. In this way the head of the bolt B will catch and rest upon the pins D D should the insulator C become broken, so as to allow it to fall. The pins D D are in turn supported by a hood E, which is adapted to cover and partially inclose the insulator. The pins D D are desirably extended through the walls of the hood E, as shown in Fig. 2, in which way they can be inserted into and withdrawn from position from the exterior of the hood. The hood E is generally made of metal, being conveniently cast into form. The socket above the bolt-head 1 is desirably filled with an insulating material, such as wax, as is also the space between the hood and insulator.

The upper end of the hood E is provided, as one arrangement, with a threaded socket 6, into which the threaded end of a hook or ring can be secured to support the hanger.

The hanger is put together by inserting the bolt B into the insulator C and then securing the hook or ring A to the projecting end of the bolt. The hood is then placed in an in-' verted position and a quantity of the wax or the like sutti'cient to fill the socket and other space is poured into the hood. The insulator is then placed within the hood, and the pins D D are inserted in the holes in the hood and insulator and riveted at their ends which project through the hood.

It will be seen that the hanger thus constructed is very efiicient. The hook A can be readily attached and CIGlZEIChGdTfIODl the bolt B. When the lamp is in position, it is thoroughly insulated by the insulatorof the hanger, so as to prevent bad results from contact or connection with the lamp. Should the insulator become broken, it will be i1npossi= ble for the lamp to fall, because the head of the bolt 13 will engage the pins D D. The hanger is held securely together without any possibilityof coming apart by the secure manner in which the pins D D can be withdrawn from the outside, the insulator C removed, and the bolt l3 removed from the interior.

hat I claim as my invention is- 1. In an insulated hanger, the combination with a holder or support for the lamp; of an insulator supporting the lamp-holder a hood covering the insulator; and devices for securing the insulator in position in the hood, said devices being arranged to act as supports for the lamp-holder in case the insulator becomes broken, and to extend through the hood so as to permit of their insertion and withdrawal from the exterior of the hood.

2. In an insulated hanger, the combination with a device for supporting or holding the lamp; of an insulator supporting said device; a hood covering and partially inclosing the insulator; and pins extended through the hood and insulator so as to secure the latter in position in the former, said pins being situated so as to engage the lamp-supporting device, should the latter be released by the breakage of the insulator.

3. In an insulated hanger, the combination with a hook or ring for-supporting the lamp; of a bolt to which said hook or ring can be detachably secured; an insulator having a depressed bearing portion for supporting and engaging the head of the bolt; a hood covering and partially inclosing the insulator; a couple of pins extended through the hood and the insulator and separated a distance less than the width of the head of the bolt; and insulating material filling the space between the head of the bolt and the hood and insulator.

4:. In an insulated hanger, the combination with a lamp-holding device; of a bolt to which the said device is screw-threaded; and an insulator havinga socket for the bolt-head, said socket being adapted to engage the bolt-head so as to prevent its turning.

In witness whereof I hereunto subscribe my name this 2l-th day of April, A. D. 1000.
